Wan Shi Tong, Librarian

Two draws stapled to the same body pull in opposite directions, which is the design problem this bird solves. The X in the cost is a scaling investment: pay a lot and you enter as a fat flyer that refunds half the outlay in cards, pay a little and you flash in a cheap evasive body that still grows over time. Rounding the entry draw down means you never quite recoup the initial pour, keeping the front half from being pure profit, while the counters buffer the flimsy printed 1/1 so it survives long enough to matter. Its passive is what turns a value creature into a policing piece: fetchlands, tutors, and any library search an opponent runs each feed it a counter and a card automatically, punishing exactly the manabases and toolbox decks that lean hardest on rummaging through their own decks. Flash is what lets the punishment arrive on schedule: hold it up, cast it during an opponent's turn, and it is already on the battlefield the next time they crack a fetch or run a tutor, catching the trigger rather than watching from your hand. Vigilance lets it swing without dropping its guard, keeping the attack and the block on the table at once while the passive draw ticks along untouched by tapping. It is a soft tax dressed as a spirit bird, kin to the old anti-search hosers but rebuilt so the punishment scales with an opponent's greed rather than shutting the engine off outright.
